Convulsion as a possible manifestation of vitamin D deficiency rickets in infants one to six months of age.

During the 42 months of January 1985 through June 1988, five infants between the ages of one and six months had hypocalcemic convulsions associated with vitamin D deficiency rickets. Despite abundant sunlight, convulsions as a manifestation of vitamin D deficiency in young infants are not uncommon in Saudi Arabia and should be considered as a probable cause for hypocalcemic seizure in breast fed infants.
